Fig. 8 is an enlarged fragmentary sectional detail on the line 8-8 of Fig. 2.

Fig. 9 is a detail of the propeller, hub and frame ready to go together.

The main frame 1 is a long stick rectangular in cross section and straight longitudinally. Round wooden pins 2 and 3 are inserted horizontally through the stick 1 half way between the center and the front end. Flat braces 4 and 5 are fixed vertically in the ends of the round pin 2, and similar fiat braces 6 and 7 are fixed vertically in the ends of the round pin 3. A pintle 8 is formed upon the forward end of the stick 1. A pintle 9 is formed upon the rear end of the stick 1. Transverse holes 10 and 11 are formed horizontally throu h the stick 1 near its rear end. Vertical oles 12 and 13 are formed through the rear end of the stick 1 in positions to miss the holes 10 and 11. A hook 14 is fixed in the stick 1 to extend upwardly in front of the hole 13.

In preparing the parts for packing and shipping the parts 1 to 14 are made up and produce the integral assembly 15, and the assembly is placed in the box A.

The front board 16 has an opening 17 to receive the pintle 8, and an opening 18 to receive the spindle of the propeller. The front board 16 has a straight lower side, straight vertical sides, and a round upper side. The rear board 19 has an opening 20 to receive the pintle 9. The board 19 is rectan ular in front or rear elevation. The front board 16 and the rear board 19 are placed together in the box A and make an assembly 21, said assembly being held in the box by a hook 22.

The horizontal tail wing frames 23 and 24 are formed of wire and are substantially U-shaped, and the frame 23' is inserted into the openings 10 and 11 from one side, and the frame 24 is inserted into the openings 10 and 11 from the other side, and the two frames 23 and 24 are placed together and form the assembly 25 and are secured to the box A by fasteners 26 and 27.

The box A is rectangular in plan and has a bottom 28 and arim 29 extending upwardly from the bottom-all the way around and the parts of the aeroplane are secured to a cardboard 30 which fits upon the bottom 28. The fasteners 26 and 27 are thin strips of soft metal bent around the wires 23 and 24 l and inserted through the cardboard 30 and having the ends bent outwardly. The vertical tail wing frame 31 is a wire similar to the wires 23 and 24 bent into an irregular U- shape, and the ends of the wire are inserted 1nto the openings 12 and 13. The tail frame 31 is placed upon the cardboard 30 and secured in place by fasteners 32 and 33.

The propeller spindle is made of wire and has a straight portion 34 and an eye The portion 34 fits in the opening 18. The propeller spindle 34 is placed upon the cardboard 30 and secured in place by a fastener 36. The propeller consists of a wooden hub 37 and propeller blades 38 and 39 of wire and fabric or paper. The hub 37 has transverse holes 371 and 372, and the wires 373 and 374 are cut to the desired lengths bent U-shape and twisted to make frames for the blades, and the ends of the wires are inserted in opposite ends of the holes 371 and 372 and glued in place, then the wires are covered with a thin cloth or a tough paper. The propeller is placed upo'n the cardboard 30 and secured in place by fasteners 40 and 41.

The straight portion 34 of the propeller spindle is inserted through the opening 18 and through the opening 42 in the hub 37, and the end 43 of the portion 34 is bent downwardly and driven into the wood of the hub 87, so that the propeller will not turn on the spindle. The rubber band 44 is hooked into the eye 35 and the hook 14, and the tension of the band holds the hub 37 against the front face of the front board 16.

lVhen it is desired to operate the aeroplane and have the propeller operate, the propeller is first rotated to twist the band 44 to the desired extent, then when the propeller is released the tension of the band will rotate the propeller. The rubber band 44 is placed in a package The cord 46 is glued to one of the upper corners of the rear board 19 and extends through notches in the upper corners of the braces 4 and 6, and over the corresponding corner of the front board 16 and diagonally across the board to the opposite lower corner and backwardly through notches in the lower outer corners of the braces 5 and 7 and backwardly to the rear board 19, and the cord 47 is secured to the opposite corner of the rear board 19 from the cord 46 and eX- tends through notches in the braces 5 and 7 over the corner of the front board 16 and diagonally across the board and backwardly through the notches in the lower ends of the braces 4 and. 6 and backwardly to the opposite lower corner of the rear board 19 from the cord 46. The cords are drawn taut and glued to the parts with which they contact. 1 The glue is made up in a package 48.

The frame thus produced is covered with tough paper 49, the paper being glued in place upon the strings and other contacting parts.

In Fig. 3 I have shown the parts in posi tion to come together, and in Fig. 4 I have shown the complete frame.

The lifting plane frames 50 and 51 are substantially alike and are made of wire and the two frames are put together upon the cardboard 30 and form the assembly 52, and this assembly is secured to the cardboard 30 by fasteners 53 and 54. The lifting plane frames 50 and 51 are to be covered with tough papers 55 and 56 glued in place, and the lifting planes thus producedare attached to ce'ntral supports 57 and 58 and to outer supports 59 and 60. The central supports 57 and 58 are substantially alike and each support is a round stick bent to form a U and has braces 61 connecting the two sides of the U 1 :ar the center.

The braces 61 are formed of thin sheet metal and the ends of the metal are bent around the stick and openings 62 and 63 are formed through the metal. The ends of the pins 2 and 3 extend beyond the braces 4, 5, 6 and 7 and those extending ends are inserted through the openings 62 and 63. The lower plane is placed against the bottom of the main frame and the upper plane is some distance above the main frame.

Clips 64 and 65 secure the supports 57 and 58 to the upper and lower planes. The clips 64 are formed as shown in Fig. 6 and comprise portions 66 and 67 embracing the stick of the support and portions 68 and 69 embracing the edge of the lifting plane. The clips 64 are shown in Fig. 7 and comprise a portion 70 embracing the up er end of the support and the portion 71 em racing the edge of the lifting plane. The clips 64 and 65 are made of tin cut to the desired shape and the clips are placed in the pack age 45, and the cords and wires are placed in thepackage 72 and the package 72 is placed upon the cardboard 30 and the supports 57 and 58 are placed together with the braces 61 extending across the package 72 thus making the assembly 73, and fasteners 74 and 7 5 are applied to hold the as sembly upon the cardboard. Openings 76 are formed through the supports 57 and 58. Wheels 77 and 78 are placed against the supports, and a wire 79 is inserted through the openings 76 and through the wheels and the ends of the wire bent to hold the wheels in place. The wheels 77 and 78 are placed upon the cardboard 30 and held in place by hooks 80 and 81. I

The supports 59 and are substantially alike and are similar to the supports 57 and 58 only slightly shorter, and the supports 59 and 60 are held in place by clips 82 and 83. The clips 82 are similar to the clips and the clips 83 are similar to the clips 64. The supports 59 and 60 are placed together. A rubber band 84 is placed around the sides of the supports and the packages 45 and 48 are inserted through or under the rubber band thus making the assembly 85 secured in place upon the cardboard 30 by fasteners 86 and 87.

It is proposed to make the parts and pack the parts in the box A, as in Fig. 2, for handling, transporting and selling and to include in the box full instructions for putting the parts together. The other uses and advantages are obvious.

, Various changes may be made Without departing from the spirit of my invention as claimed.
